Well, I really don't regret my purchase of the Windows 7 Pro full edition, yeah some folks got it cheaper, but I just can't help but feel I'll get my use out of it. Windows 7 will most likely be the standard for a minimal of three years, if not longer. I can use the license I purchased for that whole time and behind. Plus, as service packs come out, I can slipstream the service packs into my copy and continue to re-use my license, far beyond when my current Dell E6400 has been replaced. Just my two cents.
